I may have stumbled on to something here, My 01 1500 318 used to get 12.5 to 13 mpg, now I am getting as of today 15.5, as the weeks go by I hope to be getting 17 to 20, laugh if you want, my wife is getting better mpg with her 96 intrepid. If you want to know email me. tjzimr@yahoo.com

 

what made the "big" jump in your mpg? hit the highway a few more miles than usual?
why would we laugh at a car getting better mpg than a full sized 4x4 truck with oversized tires?

 

why not jsut post your big secret

 

not that 15.5 is all that impressive. had he said 20-25, or 100mpg, now then you would have my full attention.

 

I would kill for 15.5 mpg, who else with a second gen gas job is getting better than that?

 

Really? I get 13.5-14 now, all city. I never hit the highway.
1500 QC 4x4 5.9L

Edit: I used to get 10-11 before rebuilding the tranny, new cat and new O2's, and new tires 265/75/16

we are getting 15+ around here.. https://dodgeforum.com/fb.asp?m=1152669

 

I get 12-13 on the highway and 7-9 in town. I couldn't get over 14 if something else was pulling me[:@]

 

I get 10-11, all in town, usually. I might try changing out my oxygen sensors here soon, see if that makes any difference. Then maybe some of my other sensors... never know when one dirty sensor is going to foul everything else up.

 

Changed mine a bit ago, I think it gets better milage because my wallet is lighter now.

 

I will tell you all, when I get home from work today.
